Every tracked fact about the two, side by side - prices, history lows, ratings and measured tuning. No verdict: which one to buy is the visitor's decision, always.
Both sides are earphones. The rows below are the facts each store publishes for this shelf - type, form factor, connectivity, codecs, mic and playtime. A dash means the listing does not state that spec.
Both curves are real community measurements (gold: JBL TUNE 120TWS-Truly · blue: JBL Tune Flex - True). Each is level-aligned to its own 200 Hz–1 kHz mean, so rig offsets don't skew the comparison.

Average level per band, relative to that curve's own 200 Hz–1 kHz middle - a taller bar plays louder there on the measured files. Same colours as the chart above.
Wearing your own earphones or headphones? Pick them here and the player pre-corrects for their sound, so the demo plays the target tuning itself - not both mixed together.
Same signal through both tunings at once - slide to blend. Start on pink noise for the clearest read.
